I just ran a series of renders using EZSkin and modifying only the blinn node values to achieve as realistic an outdoor render with a 3 point lighting system. 

Infinite light, 85% intensity, shadows @ 50%, key light
Envsphere, no image, gamma settings @ 1 on the material zone, not visible to camera, fill light.
Spot light, 42% intensity, Inverse Square attenuation.

Miki 3 was my subject, skin texture maps and morphs used from the Beautiful Asian package.  I rendered from default EZSkin through blinn shader node tweaks, just adjusting blinn values as mentioned before.
